Most recent results on dark matter: "No".
The galaxies could have been spinning
long before star formation, the whole
entire giant frame.
As well there could be effects of "solar
pressure" between systems where the gravity,
as it were, of the entire system already
was in a balance before the dust swept
into the critical points and formed stars.
At the borders of those frames the net
gravity would be about zero and solar
pressure, as it were, would be significantly
stronger in comparison than when it was in
the gravity well.
A notion of fall gravity or the LeSage-ian
is not so unusual, though instead of an ether
of corpuscles that push everywhere, ("fall
gravity" as not of massive bodies but also
of them) instead the notion here has the origin
is everywhere (i.e., for each inertial frame)
and everything is always falling to it.
Then mass defines inertia then that so happens
to interact with a constant uniform gravific
field everywhere.
I realize this is simplistic and somewhat under-
informed, but it's a mathematical approach.
